Read this on redcafe.net and I'm currently doing a bit of research at some Jap website since I can read Jap..
Looks like it's just a rumor..
Also posted on redcafe.net was
In a Japanese TV show in June, Kagawa admitted that his "dream date" would be celebrity actress Masami Nagasawa, said he "has been in love with her for 23 years".
Seems possible given that some top Japanese sports star did marry AV stars..
But given how reserved and quiet Kagawa is, I'm starting to lean towards the Masami Nagasawa party because this is shinji-rarenai (unbelievable in Japanese).
What's your thought??
